Has anyone used one?
And what does it do?

 

The procal tuner is typically used to adjust settings for wheel size, gears, daytime running lights, engine idle for winching etc.. Very helpful after a lift I had one with an 08 I had and it was great, I eventually went with a superchip tuner later which did more engine tuning. Research what they do and buy accordingly, remember that they vin lock which means that once u use it on your vehicle until the procal is set back to stock it can't be used on other JK's.

 

So it is easy to use?
But pro tuner does more for engine. How much more?

 

super easy to use and cheap. for the most part, most people just use it to calibrate their speedo and turn off things like their tpms.

a programer like a superchips cannot make your 3.8 into a hemi but, it will provide noticable and real gains on top of do much of what the procal does. but, they are more expensive.

 

OK. Thanks for the info.

 

Exactly what Eddie said, the procal is fine for basic changes which suit most needs and the cost for it is great. The superchips tuner does more and less as it can't control the daytime running lights, but it did provide a better throttle response and a bit of performance gain but it's not like doing a hemi swap. Not sure what year you have for a jeep but to compare I had a 2008 2 door and loved it the superchips tuner made it even more enjoyable to drive with a better foot response. There are other plug and play options out there as well that will improve this as well. I now own a 2012 4door with the pentastar and this motor is amazing, I don't think this is even an option yet to use a superchips tuner as they will have to design and test what there program values are.

What are you trying to do/or what are you needing a tuner for? Would be a good question to ask as well more info on this would be helpful for us to answer your question if you have more.

 

Mainly tpms. I also have a 08' two door. Running 35's, so pretty sure need to adjust speedo. Will I get more out of super tuner or exhaust/ intake change?

 

Yup it will work perfect for that, the superchips tuner only let me drop the tpms down to 12 or something like that which was fine, on the procal u can drop it to 0 both of them will also fix the stability programming as well when u corner if u haven't noticed it u should when taking corners at speed.

 

I think that I will do the banks stinger package (air/exhaust) then a tuner.
You are right, that engine needs to breathe first.

 

Agreed on the opening it up to breath, it's a better option to start with to get more power. The pedal response is better and I did gain approximately a 1mpg gain with the superchips but as far as speed nothing really but it's a jeep as so speed isn't really the design behind it. If you are having trouble with power it depends on what gears u are running as well and if it's auto or stick but that's a whole desperate topic use the search and u will see how often it's discussed.
